Abstract
Disclosed is an α-phase nickel hydroxide and a preparation method and use thereof. The method for preparing an α-phase nickel hydroxide comprises the following steps: subjecting a biomass calcium source to a calcination to obtain a porous calcium oxide; under a protective atmosphere, mixing the porous calcium oxide with a first methanol-ethanol solvent to obtain a calcium oxide heterogeneous solution; under a protective atmosphere, mixing the calcium oxide heterogeneous solution with a nickel source homogeneous solution to obtain a mixture, and subjecting the mixture to a coprecipitation to obtain a nickel calcium hydroxide precursor, wherein the nickel source homogeneous solution is prepared with a nickel source containing crystal water as a solute and a second methanol-ethanol solvent as a solvent; and subjecting the nickel calcium hydroxide precursor to a calcium hydroxide removal treatment to obtain the α-phase nickel hydroxide.
